18F26K80 Code Optimisation.

[retepsnikrep]

Attached is a complex man in the middle program I have written to control my Honda hybrid car via MCP2515 CAN bus modules and a PIC18F26K80 at 64mhz.

It works well in the car presently but I'm keen to see if I have missed any obvious pbpro speed tricks.

I would be grateful for any comments or observations from the gurus on here.

I did try and get the pic to run at 80mhz with an external 20mhz resonator and 4xPLL but it just would not run/work.
There was a separate thread for the overclocking attempt. Maybe a bad pic or bad resonator etc at my end.

I'm thinking about adding a timer program loop counter so I can see what effect ideas people have have on the basic loop time.
Thanks in advance for any speedup or space saving ideas.
